Rockworld TV was a British television channel which featured rock music, and was aimed to highlight "underground" lifestyles and artists.

Officially it was only on the air from 6pm until the early morning, although previews ran during the rest of the day (apart from a few hours of Teleshopping programmes), making Rockworld effectively a 24-hour channel.

Non-music programmes included the anime series Cromartie High School and Gilgamesh, Dave Vanian's Dark Screen (an amateur horror film showcase) and Peek-A-Boo, interviews with artists and fetish models.

During February 2010, the license and slot were transferred to administrators, Alexander Poultney Limited, with a view to launching Mushroom TV's channel, Lava.

Its place on Sky Digital 378 was taken by Lava, a channel dedicated to the rock and indie music genres.
